Research shows that Coyotes may negatively impact White-tailed Deer recruitment rates by preying on fawns during the summer months. In the Tensas River National Wildlife Refuge, Coyotes exhibited different prey selection between pre-fawning and fawning seasons, leading to changes in consumption patterns of White-tailed Deer and small mammals.
Canis latrans (Coyote) is known to influence herbivore communities through predation. In particular, Odocoileus virginianus (White-tailed Deer) recruitment rates on the Tensas River National Wildlife Refuge in northeastern Louisiana may be negatively influenced by Coyote predation on fawns during summer months. Tensas River National Wildlife Refuge is mostly bottomland forest surrounded by agricultural croplands and, although Coyote diets have been extensively studied, prey selection in bottomland forests is poorly understood. We collected scat samples within Tensas River National Wildlife Refuge to determine food habits of Coyotes. Coyotes used prey differently between pre-fawning and fawning seasons and exhibited inverse consumption of White-tailed Deer and small mammals by season. Consumption of White-tailed Deer increased similar to 27% from the pre-fawning to fawning seasons, whereas consumption of small mammals decreased similar to 21% . These findings are an important first step towards understanding prey selection by Coyotes in the Lower Mississippi Alluvial Valley.
